Plant and algal cell walls: diversity and functionality.
BACKGROUND Although plants and many algae (e.g. the Phaeophyceae, brown, and Rhodophyceae, red) are only very distantly related they are united in their possession of carbohydrate-rich cell walls, which are of integral importance being involved in many physiological processes. Furthermore,wall components have applications within food, fuel, pharmaceuticals, fibres (e.g. for textiles and paper) ...
متن کاملElicitor-Active Oligosaccharides from Algal Laminaran Stimulate the Production of Antifungal Compounds in Alfalfa
Natural polysaccharides w ere exam ined for their activity as elicitors o f phytoalexins and flavonoids in alfalfa cotyledons. O nly tw o polysaccharides, lam inaran and pectic acid, had e lic itor activity. Laminaran, w hich was m ore active than pectic acid, was hydrolyzed by tunicase and the hydrolysate was subjected to charcoal and gel filtration colum ns. Introduction o f the pyridylam in...
متن کاملSulfated Oligosaccharides Mediate the Interaction between a Marine Red Alga and Its Green Algal Pathogenic Endophyte.
The endophytic green alga Acrochaete operculata completely colonizes the sporophytes of the red alga Chondrus crispus; however, it does not penetrate beyond the outer cell layers of the gametophytes. Given that the life cycle phases of C. crispus differ in the sulfation pattern of their extracellular matrix carrageenans, we investigated whether carra-geenan fragments could modulate parasite vir...
متن کاملMass spectrometry of oligosaccharides.
Glycosylation is a common post-translational modification to cell surface and extracellular matrix (ECM) proteins as well as to lipids. As a result, cells carry a dense coat of carbohydrates on their surfaces that mediates a wide variety of cell-cell and cell-matrix interactions that are crucial to development and function. Because of the historical difficulties with the analysis of complex car...
متن کاملEnzymatic synthesis of oligosaccharides
The biological interest of oligosaccharides is growing very rapidly, and necessitates the development of efficient synthesis reactions. The stereoand regio-selectivity of enzyme catalysis is a key advantage in this field, as a complementary tool to the chemical approach. Two types of enzymes can be applied to the obtention of oligosaccharides: Hydrolytic enzymes, which can catalyze either rever...
